New hope for patients with psoriasis from planar shock wave treatment
An estimated 25 million people around the world are affected by psoriasis. In Germany alone, between two and three million people (2-3% of the population) suffer from this unpleasant skin disease.

There are various therapeutic approaches for alleviating symptoms, including topical treatments with salicylic acid, urea, polidocanol, tar, dithranol, cortisone and Vitamin D and A derivatives. Systemic treatments include methotrexate, corticosteroids, immunosuppressants, fumarates and biologicals. In addition to various alternative medical treatments, such as acupuncture and homeopathy, bath, light and climate therapies also represent promising treatment approaches. In addition, the precise application of a special laser light to the affected areas is now considered a standard treatment.
The first attempt to use planar shock waves to treat a patient who had been suffering from psoriasis vulgaris for many years was undertaken in October 2006.
Shock waves are rapid sound waves which trigger a biological response in treated tissue and can thus give rise to a range of effects. Details of the mode

To evaluate treatment outcome, photos of the psoriatic plaques were made prior to the first treatment session and after the final (5th) treatment session.
Evaluation of the photographs shows visible improvement to the psoriasis after just 4 treatments, i.e. within 8 weeks. Scale formation, the core growth phenomenon, is significantly less pronounced and the margins of the lesions are no longer so sharply delineated. Signs of healing are clearly visible.

A further observational study with more patients is planned to confirm this result.
